Impatiens damrongii Shimizu, Acta Phytotax. Geobot. View in CoL 24: 38 (1969); S. E. Asian Stud. 8, 2: 215 (1970).

Type: Thailand, Phitsanulok Province, Phu Miang mountain, Shimizu, T. 11634 (holotype KYO!, isotype BKF!). Figure 3A–C View Figure 3 .

Impatiens wenshanensis S.H.Huang, Acta Bot. View in CoL Yunnan. 25, 3: 267–268, pl. 3, f. 1–7 (2003), syn. nov. – Type: China, Yunnan Province, Wenshan, Laojunshan, 1820 m, 23 ix 1992, Y.M. Shui 0254 (holotype YUKU n.v.).

Distribution. This species occurs in Louangphabang Province, close to the type locality in Phitsanulok, Thailand, and in Yunnan Province, China, where it was originally described under Impatiens wenshanensis ( Huang, 2003) .

Habitat and ecology. Impatiens damrongii was found growing in shaded and mixed bamboo to deciduous forest in limestone areas, 300–500 m altitude, associated with Amorphophallus sp. ( Araceae ), Curcuma corniculata Škorničk. ( Zingiberaceae ), Argostemma sp. ( Rubiaceae ) and Dendrocalamus sp. ( Poaceae ).

Phenology. Flowering from October to November, fruiting from November to December.

Specimen examined. LAOs. Louangphabang Province: Long Lao Mai village , 19°45′18.4′′N, 102°02′59.8′′E, 900 m altitude, 5 xi 2012, Souvannakhoummane, K. & Phoutthavong, K. KS492 ( HNL, QBG, spirit collection at Pha Tad Ke Botanical Garden) GoogleMaps .

Vegetatively, this species is close to Impatiens clavigera Hook. f. but differs in having dentate-glandulate outer lateral sepal margins and a large thick crest in the dorsal petal. The type drawing and original description of Impatiens wenshanensis match the protologue of I. damrongii well.
